A projectile is fired vertically upwards with an initial velocity u. After an interval of \( T \) seconds a second projectile is fired vertically upwards, also with initial velocity \( u \)
(a) They meet at time \( t=\frac{u}{g} \) and at a height \( \frac{u^{2}}{2 g}+\frac{g T^{2}}{8} \)
(b) They meet at time \( t=\frac{u}{g}+\frac{T}{2} \) and at a height \( \frac{u^{2}}{2 g}+\frac{g T^{2}}{8} \)
(c) They meet at time \( t=\frac{u}{g}+\frac{T}{2} \) and at a height \( \frac{u^{2}}{2 g}-\frac{g T^{2}}{8} \)
(d) They never meet
